中文摘要 | 本試驗以3種不同材質產生之光環境,調查粉蝨入侵發生及病毒病害發生之進程。調查結果顯示,粉蝨在番茄定植後即開始入侵,經2-3週密度大幅增加,同時快速傳播病毒病害。在阻隔UV的環境下,粉蝨發生數量及罹病率明顯減少,病毒病害發生的時程往後延長。秋冬季調查結束之發病率分別為一般PE膜54.3%、高折射率PE膜61.7%、阻隔紫外光資材25%,春夏季之發病率則分別為88.6%、98.1%、43.3%,顯示阻隔紫外光環境不利粉蝨傳播病害。三處理下番茄的開花日數、結果率、單果重都無顯著差異,始熟日數則較2種農用膜約晚1週。在未採行防治措施下,總花序數尚可符合農友生產需求。以上結果顯示阻隔紫外光環境有利於管理番茄粉蝨類及其傳播之病毒病害。 |
英文摘要 | This study conducted three kinds of light environment to investigate progress of whitefly invasion and viral disease occurrence. Results revealed that whitefly invasion would begin soon after tomato transplanted. Its density could increase rapidly after 2 -3 weeks and then transmit viral disease simultaneously. Under UV-blocking environment, average number of whiteflies trapped on yellow-sticky traps was lower significantly. Viral diseases also proceed at slower pace. Virus infection-rate during fall and winter periods was 54.3% in polythene films, 61.7% in light scattering polythene films, and 25% in UV-blocking material. Results during spring and summer periods were 88.6%, 98.1%, and 43.3% respectively. These results indicated UV-blocking environment was unfavorable to whiteflies and viral disease it transmits. Characters such as percentage of fruit setting, days to flowering, average fruit weight of tomatoes in each treatment were not significantly different. Days to maturation of tomatoes were 1 week later under UV-blocking environment compared to the other treatments. Average truss number also could reach production requirements of farmers without any pest control strategy. Our results suggest that UV-blocking environment would be suitable for management of tomato whiteflies and viral disease it transmitted. |
